I've owned a similar Bissel steam mop for about 6 months. At first it worked very well, and I was pleased with the results. However, it started leaking between the water tank and the filter. Today, I had to wait between doing my bathroom and kitchen floors, and when I was ready to go again, ALL of the water had leaked out. I added water to the tank and made sure the cap was closed tight and correctly seated, but the water just ran right out. I googled the problem and found a lot of advice to replace the o-ring, gasket, etc. But mine is fairly new and not cracked or anything. So I investigated and realized the clear tube in the water tank was putting pressure on the gasket. When I removed the clear tube and screwed everything together, viola, no leak. Reasoning that the tube was there for some function, I didn't want to just leave it out, so I trimmed it a little, reassembled, and tested. NO LEAKS! I'm thrilled because otherwise this is a great product. It does a great job cleaning hard floors. I like that I can use plain water and still be killing germs.
